Previously Ai was given a necklace by Alex that is a Mystic Code. An item that enhanced her strength, speed and durability. So I highly doubt her stalker-killer from canon can actually do something with this idol that made her a bit stronger than your average human. Not that I care, I'm still waiting for this to happened and let it be over with. Let Alex or Lorelei handle this idiot. Might even made this supposed killer erased from public records so that no one would bat an eye to someone like this at all. TORTURE COMMENCED!
